vid e abottlecap embodying a construction somewhat similar to that shown in my Patent No. 2,392,912, butdiffering th'er'eover in the provision o'f1'a.rsiinplified assembly of the'ncapr and t'he securing means associated therewith.

A further important object of the invention is the inclusion of a 'fiex'ing member within the cap proper so arranged astotend to oppose seatingot the cap in the neck. of a bottle thusei fectmg 'a constant tension upon the securingime'ans whennen-gaged with the bottl'e;."and efi'e'ctinga positive gasti ht seal.

A still further object of the. invention is the provision of a compressible bottle closure in which slots are formed therein rzfor reception of bai'l members the slots. being. of such dimensions as to filmly grip and hold the bails against displacemen Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a perspective view of one form of the cap. Figure 2 is a fragmentary elevation partly in section of a bottle having the stopper engaged therewith in closed position.

Figure 3 is a fragmentary elevation of a bottle having the stopper engaged therewith in released position.

Figure 7 is an enlarged fragmentary cross section illustrating the connection of the bail members and the clamp.

Figure 8 is a top plan view of a modified form of the stopper.

Figure 9 is a bottom plan view of the flexible disk cap employed in the stopper.

Figure 10 is a side elevation thereof.

There is illustrated a portion of a beverage bottle I!) of conventional form, in which an annular groove H is formed below the mouth I2.

The cap I3 is molded from rubber or other plan view of the cap shown in resilient material such as certain plastics. The

cap is of a diameter greater than the mouth l2 of the bottle and includes an axial stopper I 4 of slight depth, and as best seen in Figure 6, the

2 Claims. (Cl'. 215-45) peripheral edge l5 of the'stopp'er H is arcua-te shaped "gra'dualiywmergingupwardly'into theoap proper.

Molded with the cap 13' and the stopper lit there-is aresilient' metallicdisk 16 consisting er a convex body portion l1 circumscribed bydbwnwardly directed spaced legs l8 integrally-formed with the bo'dy portion. "The legs -l 8"lie 'in substantially parallel relation with the periphery 2035 the stopper 'l l, which under compressive'ferce will tend to expand thestopper circumferentiallyintosnugengagement with the moutli oi the bottle, as will be more 1 fully explained; In the "form of the cap shown in' Figural; the "cap it isformed with "a pair [of right angular channels 119 of a depth 'stoppingabove'the horizontal smedial portion of the cap and of a width less than .therdiaimeter \of'respective' bail members an, an d'ascbestseeniini Figure 6,;t-h'e bail members are: substantially U-shapedthe bight portion. 21 a being of a width so as to present respective leg members 22 upon opposite sides of the neck of a bottle when the cap is engaged thereon, the bight portions 21 being disposed in respective channels 19, and by reason of the greater diameter of the bail members 20, the latter will be securely retained within the channels. From the foregoing, it will be seen that the cap and bail members may be separately formed and later assembled, thus greatly simplifying manufacture of the device.

By reason of the right angular arrangement of the channels IS, the bight portion 2| of one of the bail members is formed with an open loop 2| to accommodate the bight portion of the other bail member.

The leg members 22 are each formed with an eyelet 23 at their extremities and receive a divided clamping ring 24 therethrough. The legs 22 are of such length as to position the ring 24 in the groove H of the bottle, for a purpose as will appear.

The ring 24 is formed with circumferentially spaced loops 25 positioned so as to receive respective eyelets 23 therewithin, and as may be seen in Figure 4, the loops 25 are outwardly disposed with respect to the bottle neck so as to accommodate the thickness of the material forming the eyelets. By interlocking the bail members and the clamping ring in this manner, the bail members are held against slippage and insuring a straight downward pull upon the cap when the latter is seated in the bottle mouth.

The ring 24 has a hook member 26 at respective ends arranged in opposed relation to one another and receive respective eyelets 21 of a cam lever 28. The operation of the cam lever 28 is well understood in the art, and a detailed explanation is not believed necessary, except to state that when the lever is moved downwardly so as to rest upon the neck of the bottle, as in Figure 2, contraction of the ring will have been effected, drawing the ring snugly into the groove H of the bottle. As the ring is contracted there will be a downward pull upon: the'legs 22, thus drawing thefstopper l4 into the mouth of the bottle. Such downward pull upon the cap will flex the disk I6, forcing the legs l8 circumferentially outward, forcing the peripheral wall l5 of the stopper firmly against the wall of the mouth I2, to effect a positive gastight seal. 1

A modified form of the stopper is illustrated in Figure 8, wherein the channels l9 are arranged in parallel relation. The parts corresponding to.

those previously described are indicated by primed reference characters.

While I have shown and described preferred constructions, this is by Way of illustration only, and I consider as my own allsuch modifications in construction as fairly fall within the scope of the appended claims.

- lc a zyp 1. The combination of a ,bottle having a neck and a mouth and a groove formed therebelow, a resilient cap member having a medial stopper, said cap further having a pair of. channels in the upper-face thereof, a bail member in each channel, saidchannels being of a width less than the diameter of the bail members and of a depth to enclose said ball members for a major portion of their length, each bail member having a pair of legs adapted to extend beside the neck of a bottle in opposed relation, each leghaving an eyelet at its lower end, a divided ring disposed through the eyelets and having respective looped ends, said ring normally occupying a position slightly above the groove of the bottle, cam means operatively connected with the looped ends of said divided ring for contracting and drawing the divided ring into said groove and effecting a downward pull upon said legs, and a resilient disk embedded in said cap, said disk having downwardly disposed circumferentially spaced legs adjacent the pe riphery of said stopper.

2. A bottle cap comprising a resilient cap having a pair of channels in the upper face thereof, a bail member disposed in each channel, said channels being of a width less than the diameter of the bail members and of a depth to enclose said bail members, whereby to hold said bail members .within the channels, each bail member having downwardly extended leg portions terminating in eyelets, a divided ring engaged through respec-' tive eyelets of the leg portions and having respective looped ends and cam means operatively engaged with thelooped ends of the ring for contracting the latter. around the neck of a bottle and exerting a downward pull upon the leg portions of the bail members. i
